This is just too intelligent; it specifically targets the offensive features and guns while explicitly excluding all other guns by name, brand, type and design. it will never get the support of the current idiocracy congress. it's a pity because it's actually a good approach which could work because unlike every other proposal to date, it makes sense even to NRA supporters.

"...The bill had three main components. The first was a list of well-known, deeply feared guns that were banned by name (like Uzis). The second banned the future manufacture and sale of any new semiautomatic weapon with a detachable magazine and more than two of several assault-style features (like a forward handgrip). The third and most critical section was Appendix A, which listed every single hunting rifle and shotgun in use at the time â€” there were hundreds â€” that didnâ€™t run afoul of the features test in the second component. Those firearms were unequivocally exempted from the bill.

At the time, gun-control advocates resisted the incorporation of Appendix A. But the idea behind it was and remains crucial to making any meaningful changes in Americaâ€™s gun laws. They must gain the support of gun owners, most of whom are heartsick over senseless carnage.
By explicitly protecting hundreds of popular sporting guns, the bill enabled senators and representatives to push back against the tide of protests â€” many of them generated by the National Rifle Association â€” at town hall-style meetings in their states and districts. They could show their constituents that their ordinary hunting rifles and shotguns were protected in Appendix A or that their guns could be added to it, if need be. Proponents of the legislation distributed blue booklets describing all three parts of the bill, including pictures of the assault weapons banned by name and the full list of guns protected by Appendix A...

its too general and therefore too easily exploited to target devices never originally intended or agreed upon by the original bill. the SFO proposal was acceptable because it was so specific; it targeted specific devices the way the FDA targets specific drugs.
